Thunder Dragon is one of the winners of the 2003 Coro Coro HMS Beyblade design contest, the other winner was Sea Dragon. It was the first Beyblade to use a CWD.

Name Change

Hasbro released Thunder Dragon as Thunder Serpent.

Bit Protector (BP): Thunder Emblem

The Bit Protector of this Beyblade is Thunder Emblem. It is the second mold version of Bit Protectors.

Attack Ring (AR): Spark Dragon

Weight Disk (WD): CWD Free Survivor

Main article: Weight Disk - CWD Free Survivor

  • Weight: 17 grams

CWD Free Survivor is the one part that can truly make Thunder Dragon a worthy purchase. CWD Free Survivor has an almost identical design to the Survivor Ring of the Dark Series of plastic Beyblades, except that it is free spinning as the name implies. With its circular form, CWD Free Survivor is a welcome addition to many types of Beyblades. It can protect against Upper Attack, and is heavier than even Circle Heavy.

Ideally, it should be used with the heavier CWD Metal Part from Sea Dragon's CWD Defense Ring, though the fact CWD Defense Ring generally serves the same purposes as CWD Free Survivor should be considered if on a restrictive budget.

Use in Defense Customization

You can build a nice, heavy Defense customization by utilizing CWD Free Survivor. For ideal performance, the RC should be somewhat worn to increase grip.

Running Core (RC): Metal Weight Flat Core

Main article: Running Core - Metal Weight Flat Core

  • Weight: 3 grams

Metal Weight Flat Core can be considered an upgrade to Gaia Dragoon MS's Flat Core. The added weight on the interior of the RC makes it slightly heavier, and moderately increases its survival and controllability compared to Flat Core. However, this is where the differences end; Metal Weight Flat Core has the exact same design as Flat Core in all other respects.

Mold Variations

The Takara Metal Weight Flat Core has a wider tip than the one that Hasbro produced. This results in a higher movement speed in the Takara version.

Use in Upper Attack Customization

Metal Weight Flat Core is not the most desirable choice out there for Attack types, but it can be used.

  • AR: Slash Upper (Slash Riger MS)
  • WD: Circle Wide
  • RC: Metal Weight Flat Core (Thunder Dragon)

Other Versions

Thunder Dragon - HMS Random Booster ACT 1 Version (Black, Prize Beyblade)
Thunder Dragon - HMS Random Booster ACT 5 Version (Off White)



Aside from CWD Free Survivor, Thunder Dragon does not have a lot to offer, and even CWD Free Survivor has been outclassed by other parts. If you already have CWD Defense Ring, or even CWD God Ring from Shining God MS, there is no reason for you to buy this Beyblade.
